ifcaro is here, pumping updates to his PKGView application for Windows. PKGView allows you to extract the contents of .pkg files of the PS3, PSP, Vita as well as those for the PSX. For those who are running homebrew on any of these devices, this tool may prove useful to you. Game patching, modding or whatever the case may be, PKGView can help you get the job done.
The new update brings support for the extraction of files from PSP and PSX packages. For Windows 7 users, you can now track the progress of PKGView while multitasking, with the new progress bar.
If you haven't already grabbed the latest version and changelog to date, you can do so below.
